Here is my xlt bench seat bottom. After I installed it, 3 people attempted to sit on it and we almost klunked heads in the middle. It is still original I believe, and looks good. I want to keep it, but I have to do something to fix the squishyness of it! Does anyone know if it looks like its missing springs or something? Is there a way to stiffen it up without tearing it apart? I noticed there is rope pieces affixed here and there too...

 

Looks original except for the white rope. A sort of short term fix, that worked pretty good for me and my ol silver 77. Get some extra/spare replacement pieces of seat foam maybe some 3" or 4" thick. Put it on the springs and then take a piece of ply wood, yes plywood and use is as a "bottom panel" to hold the extra foam in place.

Make the plywood just long enough to go under the front and rear edge of the seat frame, like where the cover material white plastic clip is. Only make it like 1" longer front too rear. Drill a finger size hole in the middle of the board to help you walk is back once pushed down.

So get the foam in place, stick one side of the board under the front lip, push is down and then walk it back to get the other end under the back back lip. Make sense? Not one full width board, but in 3 pieces. Dvr side, center and then passenger.

 

Hey now, that sounds like a great idea. I will give that a try when I pull the seat back out to do the carpet. Thanks!

 

I know it sounds getto or jankie, but it worked for my ol silver trucks seat. I had some broke springs on the dvr side and the foam was shot. And it had saggy seat syndrome. So when I pulled the cover off to get the edge seam re-stitched, I just replaced the broke springs, add some extra springs and then added a layer of foam. And managed to get the cover back on. The upholstery guy showed/helped me doing a trick to getting it back on with some hard plastic strips that let the cover slide in place, then he pulled the plastic strips out.

 

Man, them upholstery guys are amazing aren't they? They're like magicians...

 

X2 on that idea.


Plywood works under a bed mattress that is too soft too.

 

And under the couch cushions....FTE... more than Ford truck tips.

 

You can buy full-width blocks of foam in different weights and carve them to match your original with an electric carving knife if you feel up to doing some upholstery work. Some foams are not very yielding at all..

 

Fix it the right way. It takes some hefty wire cutters or bolt cutters to cut these to size. And if you still want to (I recommend) replace the foam as well.
